Patented May 2, 1939 OFFIQE 11 Claims.

This invention relates to mortar dispensing or depositing devices whereby predetermined amounts of mortar may be deposited on a block, brick or the like in an improved and simplified manner.

One of the principal objects of the present invention is to provide a portable receptacle adapted to contain mortar, from which the mortar may be discharged in predetermined amounts and deposited on a block, brick or the like in an efficient manner.

Another object of the present invention is to provide a receptacle, from which mortar may be discharged in predetermined amounts, which will not become fouled by the mortar contained therein and, therefore, is efiicient in use and operation.

A further object of the present invention is to provide a mortar dispensing and depositing device whereby the mortar may be deposited on blocks, bricks or the like, in predetermined amounts and in a finished outline to thereby eliminate slow hand troweling and shaping operations.

Another object of the present invention is to provide a mortar depositing or dispensing device which is relatively light in weight and economical to'construct.

Other objects of the invention will become apparent from the following specification, the drawing relating thereto and from the claims hereinafter set forth. I

' Referring to the drawing, and referring par- 10 ticularly to Figs. 1 to 4, inclusive, an embodiment of the present invention is illustrated which comprises av portable receptacle it, generally rec-. tangular in shape, adapted to contain mortar therein. The receptacle I0 is open at its top and 15 is definedby upstanding side walls l2 and i4 and end walls I6 and I8. The receptacle Wis preferably-formed of sheet metal material and may, for example,be formed of a single aluminum casting. An opening is provided through the bottom of the 20 receptacle for discharging or dispensing the mortar therefrom. The side walls l2 and M are preferably downwardly' and inwardly inclined adjacent the bottom thereof as indicated at 20 and 22, respectively, so as to eliminate sharp corners within the receptacle and to thereby assist the flow of mortar from the receptacle and prevent fouling of the receptacle adjacent the sides thereof. The wall portions 24 and 26 adjacent the bottom of the receptacle define the sides of the opening through the bottom of the receptacle and are preferably downwardly and outwardly tapered to insure proper discharge of the mortar from the receptacle Inorder to define the design or pattern of the mortar discharged from the receptacle, depending uponthe type of block or brick upon which the mortar is deposited, a sheet metal member generally designated at 28 of proper construction and design is mounted within the bottom opening of the'receptacle. In the embodiment illustrated in Figs. 1 to 4, the sheet metal member 28 comprises transversely extending spaced members 30 and 32- which are secured together relative to each other by" longitudinally extending members 35. u The transversely extending members 32, which are mounted adjacent the ends I6 and 18 of the receptacle, preferably taper downwardly and inwarolly fora distance and then taper downwardly and outwardly to the bottom of the receptacle. Thetransverse members 30, forming the central transverse portions of the member 28, have wall portions which first diverge from each other in a 55 downwardly and outwardly tapering direction and then converge towards each other in a downwardly and inwardly tapering direction. By providing the tapering walls of the members .39 and 32 above described, the mortar within the receptacle is fed towards the spaced openings provided by the spaced members 30 and 32 and is discharged from the receptacle without fouling or sticking to the member 28 or the walls of the receptacle. The ends of the transverse members 36 and 32 are also tapered downwardly and outwardly as indicated at 34 (Fig. 2) and 36 (Fig. 4), respectively, and are also tapered downwardiy and inwardly as indicated at 38 (Fig. 2) and 45 (Fig. 4), respectively, so as to assist in the discharge and prevent fouling.

In order to control the discharge of mortar from the receptacle in predetermined successive amounts on successive blocks, a grate member 42 having transversely extending members 44 preferably formed integral with longitudinally extending side members 46 is movably mounted within the receptacle within the discharge openings provided by the member 28 and the receptacle walls. The side edges 48 of the transverse members 44 are preferably tapered upwardly and inwardly; and the side edges 50 of the longitudinal members 46 are also preferably tapered upwardly and inwardly to prevent fouling and insure proper discharge of the mortar from the receptacle.

The grate member 42 is normally in its closing position, as illustrated in Figs. 2 to 4, and is mounted for upward movement relative to the spaced discharge openings by means of transverse rod members 52 and 54 which have downwardly extending end portions 56 which are suitably secured to the grate member 42 adjacent the corners thereof.

Outstanding bracket members 58 having open slots 60 adjacent their inner ends are oppositely disposed in pairs and fixedly secured to the sides l2 and I4 adjacent the ends thereof, the downwardly extending rod portions 56 being slidably received within the slots 60.

In order to constantly urge the grate member 42 to its normally closing position, spiral spring members 62 embrace the downwardl extending rod portions 56 between the under side of the bracket 58 and the top surfaceof the member 42. In order to protect the springs 62 against fouling by the mortar contained within the receptacle and to permit the vertical movement of the grate member 42, sleeve members 64 and 66 embrace the springs 62 and are constructed in the form of a telescopic joint. The springs 62 engage the upper surfaces of longitudinally extending members 45 of the grate member 42 and also engage the under surface of the sleeve 66. As the top surfaces of the sleeves 66 engage the under surfaces of the bracket members 58, it is evident that the springs 62 constantly urge the grate member 42 downwardly to its normally closing position.

In order to limit the movement of the grate member 42 relative to the discharge openings and to thereby predetermine the amounts of mortar discharged therethrough, stop and guide members 68 are secured to the end walls l6 and I8 of the receptacle and have outstanding portions 10 and 12 which engage the grate member 42 and limit downward and upward positions, respectively. The engaging portions of the outstanding portions 10 and 12 are preferably formed with knife edges so as to prevent fouling and sticking of the grate members to the stop. Slots are preferably provided in the ends of the mem bers 46 and these slots slidably embrace the sides of the members 68 to thereby assist in guiding the grate 42 in its vertical movement relative to the discharge openings.

For transporting and carrying the portable receptacle l9 having the mortar therein, upstanding oppositely disposed ears 74 are formed with the side walls I2 and i4 adjacent the ends thereof and have secured thereto transversely extending bars 16 which form handles which may be grasped by the operator for transporting the receptacle to succeeding blocks.

Referring to Fig. 5, a building block 18 of the type for which the embodiment illustrated in Figs. 1 to 5 is particularly adapted is illustrated. The block 18 is of the conventional type having air holes 80 therethrough and provided with webs 82. The block i3 is illustrated in Fig. 5 as having had mortar 34 deposited thereon by the device described in Figs. 1 to 4. It is evident from this figure that the longitudinal edges of the block 18 and the transverse webs 82 have deposited thereon the mortar 34 in predetermined amounts and according to the design of the block T8. In operation the receptacle I0 is set upon the upper surface of the block 78 with the outlet openings of the block complementary in shape and position to the portions of the block upon which the mortar is to be deposited. After the receptacle is placed in position, by raising the grate member 42 by means of the rods 52 and 54, the mortar is permitted to flow downwardly through the discharge openings adjacent the bottom of the receptacle and flows onto the upper surface of the building block in. the proper positions. Upon raising the receptacle ll] from its position on the block, the springs 62 return the grate member 42 to its normally closing position, thereby cutting oh the flow of mortar from the receptacle.

In Fig. 6, a pin member 86 having a reduced and threaded upper end 88 is illustrated which is adapted for use with the embodiment illustrated in Figs. 1 to 4 for automatically raising the grill member 42 when the receptacle is placed in position upon a building block. Referring to Fig. 1, threaded openings 90 may be provided through the grate member 42 adjacent the corners thereof for receiving therein the threaded portions of the pins 86. The pins 86 are placed within the corner openings 90 and extend downwardly below the under surface of the receptacle I0 so that when the receptacle is placed upon the upper surfaceof a building block, the pins serve to engage the block surface; and as the receptacle is allowed to drop, the grate member 42 is automatically raised, thereby permitting the mortar contained therein to flow downwardly through the discharge openings. It is, of course, evident that the embodiment illustrated in Figs. 1 to 4 may be adapted for use either with or without the pins 86 merely by providing the openings 90; and the pins 86 may be inserted therein or removed therefrom according to the operation desired.

Referring to Figs. 7 and 8, a modified structure is illustrated which is particularly adapted for use with the conventional building brick. An elongated receptacle, generally indicated at 90, is provided with end walls 92 and 94 and side walls 96 and 9B. 7 The receptacle 90 is open at its top and is provided with an opening through the bottom thereof for dispensing mortar therefrom.

The sideand end walls adjacent the bottom of the receptacle 90 are preferably tapered downwardly and inwardly, as indicated at ifll, for the same reason as pointed out above, and are also tapered downwardly-and outwardly as indicated at N12, for the same reason-as pointed out above. The end walls 92 and 94 and side walls -96 and 98 adjacent the bottom thereof define a discharge opening Hi4 through which the mortar is discharged irom the receptacle.

In order to control the'fiow of mortar through the opening HM and to predetermine the outline of the mortar so-discharged, a longitudinally extending member N16 is movably mounted within the-opening I04 and is normally in its closing position, as illustrated in Figs. '7 and 8. The member 106 is preferably transversely curved on its upper surface to assist in the flow of mortar to and through the opening #94; and is preferably tapered downwardly and inwardly to form the bottom, as indicated at I08, to provide the proper outline of the mortar deposited upon a building brick, or the like.

A longitudinally extending rod member 3455, having downwardly directed end portions, is secured to the gate member 186 in a manner similar to the engagement of the rod members 52 and 54 with the grate member 42 above described. Resilient springs similar to the springs 52, and sleeves forming telescopic joints similar to those above described, are also preferably provided in the embodiment illustrated in Fig. 8 and are mounted for movement relative to the receptacle 90 by the brackets H2 which are similar in construction to the brackets 53 above described in detail.

In order to limit the downward movement of the member 406 relative to the opening 5%, stop pins H4 may be provided through the downwardly extending portions of the rod member l iii for engagement with the upper surfaces of the brackets H2.

Referring to Fig. 9, a conventional building brick H6 is illustrated having deposited thereon mortar I Is by means of the depositing device illustrated in Figs. 7 and 8. It is evident from Fig. 9 that the mortar H8 deposited upon the upper surface of the brick l 56 has a finished outline corresponding to conventional practice. The outline of the mortar H8 is automatically produced by the tapering under sides Hi8 of the member I06 and the finishing troweling operation, according to hand practice, is thus dispensed with.

From the above, it is evident that the present invention provides improved and simplified structures for dispensing and depositing mortar in predetermined amounts and according to predetermined outlines and designs upon the surfaces of building blocks, bricks, or the like in an efiicient manner. It is also evident that the particular outlines and designs described above are merely illustrative and that the depositing devices described above may be modified to produce other desired designs within the scope of the present invention. Formal changes may, therefore, be made in the specific embodiments of the invention described without departing from the spirit and substance of the invention, the scope of which is commensurate with the appended claims.
